[0023] Based on this, in order to solve the problem that the wave spring in the related art often deforms rapidly in some supporting and damping devices, the anti-interference ability and the carrying capacity are insufficient, the device cannot operate normally, and a safety hazard is caused, the embodiments of the present application provide the following solutions.

[0024] Please refer to Figures 1-4, including spring body 1, buffer mechanism 2 and flat ring 7, the buffer mechanism 2 includes shock pad 21 and compression spring 22, the spring body 1 includes a plurality of wave crest 11 and wave trough 12, the wave crest 11 and the wave trough 12 are staggered in wave shape in transverse direction, the wave crest 11 and the wave trough 12 of several spring bodies 1 abut each other in longitudinal direction, the flat ring 7 abuts on the spring body 1, the wave crest 11 and the wave trough 12 of several spring bodies 1 form annular ring, the shock pad 21 is arranged on the annular ring, one end of the shock pad 21 abuts with the wave crest 11 of the spring body 1, the other end of the shock pad 21 abuts with the wave trough 12 of another spring body 1, the shock pad 21 is provided with three through holes, the compression spring 22 is arranged on the shock pad 21, and the two ends of the compression spring 22 abut with the two ends of the shock pad 21.

[0025] Thus, when the wave spring is used, the flat ring 7 first transmits the pressure received to the spring body 1, the wave spring is compressed, the annular ring formed between the wave crest 11 and the wave trough 12 of several spring bodies 1 is flattened, the wave crest 11 and the wave trough 12 of different spring bodies 1 are close, the shock pad 21 and the compression spring 22 are compressed, the shock pad 21 and the compression spring 22 assist the wave spring to bear the pressure received, the deformation speed of the wave spring is reduced, after the pressure is removed, the wave spring needs to restore to the original state, at this time, due to the slow deformation speed of the shock pad 21, a tightening force is given to the wave spring, the time for the wave spring to restore to the original state is reduced, so that the stiffness of the wave spring is increased.

[0026] Optionally, in some embodiments, referring to Figure 3 and Figure 4 , the shock pad 21 is in S shape, magnets are attached to the two ends of the shock pad 21, the magnets include first magnet 3 and second magnet 4, the first magnet 3 is close to the wave trough 12, the second magnet 4 is close to the wave crest 11, and the first magnet 3 and the second magnet 4 are of the same polarity.

[0027] Thus, the S-shaped design of the shock pad 21 has advantages in mechanical properties and structural adaptability, when the shock pad 21 is impacted, the shock pad 21 can more effectively disperse and absorb energy, increase the contact area with the wave crest 11 and the wave trough 12, thereby improving the stability of the connection, after the shock pad 21 is compressed, the two ends of the shock pad 21 begin to approach, after approaching to a certain extent, the first magnet 3 and the second magnet 4 generate repulsive force due to the principle that magnets of the same polarity repel each other, the deformation speed of the shock pad 21 is reduced, and the carrying capacity of the wave spring as a whole is increased.

[0028] Optionally, in some embodiments, referring toFigure 1 The flat ring 7 and the side surface of the spring body 1 are provided with grooves, and the grooves are connected with the rolling balls 5.

[0029] In this way, during the compression and recovery of the wave spring, the spring will rub against the inner wall of the shell of the device, which will cause the gradual loss of the surface material of the spring. The abrasion will change the shape, size and precision of the spring, thereby affecting its normal work. The abrasion can also make the surface of the spring rough, increase the friction coefficient, further aggravate the abrasion process, and form a vicious cycle. The grooves are provided on the flat ring 7 and the side surface of the spring body 1, and the rolling balls 5 are arranged in the grooves, so that the original sliding friction is changed into rolling friction, greatly reducing the contact between the spring and the shell of the device, making the spring more smooth during the compression and recovery process, and prolonging the service life of the device.

[0030] Optionally, in some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 The wave crest 11 and the wave trough 12 of the spring body 1 are movably connected with the limiting plates 6, the limiting plates 6 abut against the two sides of the shock-absorbing sheet 21, and the limiting plates 6 are provided with sliding grooves, and the width of the sliding grooves is slightly larger than the thickness of the shock-absorbing sheet 21.

[0031] In this way, when the shock-absorbing sheet 21 is compressed, it will deform and generate a great elastic force in the vertical direction. At this time, if the position of the shock-absorbing sheet 21 deviates slightly, the great elastic force in the vertical direction will generate a component force in other directions, which will eventually cause the shock-absorbing sheet 21 to be separated from the wave spring body 1 when it rebounds. The limiting plates 6 are clamped on the spring body 1, and then the shock-absorbing sheet 21 is compressed to a small extent. The two ends of the shock-absorbing sheet 21 are aligned with the sliding grooves on the limiting plates 6, and the width of the sliding grooves is slightly larger than the thickness of the shock-absorbing sheet 21. The purpose is that the shock-absorbing sheet 21 can be easily inserted into the limiting plates 6. By rotating the shock-absorbing sheet 21, the shock-absorbing sheet 21 is tightly clamped between the limiting plates 6 in a sliding manner along the sliding grooves on the limiting plates 6, and the two ends of the shock-absorbing sheet 21 abut against the wave crest 11 and the wave trough 12.

[0032] Optionally, in some embodiments, please refer to Figure 1 The surface of the spring body 1 is coated with corrosion-resistant paint.

[0033] Thus, the spring can be in contact with various corrosive media such as acid, alkali, salt and the like during use. The corrosive media can cause erosion to the spring material, resulting in corrosion on the surface of the spring. By coating the surface of the spring body 1 with corrosion-resistant paint, a protective film can be formed to isolate the spring from the corrosive media, thereby effectively preventing corrosion. Corrosion is one of the main causes of spring failure, and corrosion can reduce the elastic properties and mechanical strength of the spring, making it unable to work normally. The corrosion-resistant paint includes but is not limited to a zinc layer plated on the surface of the spring to improve the corrosion resistance of the spring; the spring is placed in a phosphate solution containing manganese, iron and zinc to form a thin film of water-insoluble phosphate; and an organic substance such as paint or plastic is sprayed on the surface of the spring to protect the spring from corrosion.

[0034] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
